Aloha, I will be buying a digital rebel SLR (the cheap one)this week. I am unsure of lense types. I will be shooting landscapes and whales etc from a distance (I live on Maui). As many know it is very bright out here and of course reflection from the water maybe a problem. Any ideas on lenses and apertures? I am new at this so I don't want to go to the store and get taken so your advice is much apreciated. Also while at the store is there any negotiating like packaging things together? I see things on ebay all the time packaging stuff. Any difference between a sigma and canon lense? Should I get the lense that comes with the camera? I also have a film rebel that I bought in 94. I don't use it much but I may start to I am assuming these same lenses will fit that camera as well?
